Bike with a guide dog? 🚴🦮

My partner and I been talking about getting a bike for both exercising and transportation. Tandem is the obvious solution, but it’s much harder to find a good one for a reasonable price, and we’d need another bike for him to to go for a ride on his own.
We have a pretty decent bike path network separated from vehicles, so the original idea is I follow behind on my own bike with him riding in front with an audio beacon, plus some verbal cues of what’s coming up.
Then we realize the little changes on the ground would be hard to identify, and having a quick enough reaction time to avoid all pedestrians would be another problem.
I currently get around with a cane with decent speed and accuracy, but can obviously do better following a person, since I don’t have to worry about where to go, just what I’m stepping on.
I’ve never worked with a guide dog, but I’ve seen friends precisely avoiding people, trees, signs, cars etc. with theirs.
So what if I replace the cane with a dog, only ride in quiet and familiar areas, and start with following another bike?
Is this a somewhat feasible idea that a school would be willing to work with, or am I crazy?
